Hello i work long time with couchbase and now with the added cbq-engine it gets more importent then ever.
Couchbase Protocol Chooses ip’s i have servers with ssh vpn and sometimes i even use docker containers and that i am expirmenting a lot.
Now i got a Situation that i would call a Bug:
i have couchbase running on 192.168.1.1 the same server has a ssh tunnel to 10.0.0.100 and also a local address that is 10.0.0.200 now when i access the server and data via the Node.JS sdk he will use 192.168.1.1:8091 via couchbase protocol but for any reason for iquerying 10.0.0.200
so on that server 
querys dont work anymore without supplying the secund address 10.0.0.200 that addresss was not supplyed to the couchbase instance via its local machine he only knows it because the XDC replica
i have a XDC connection via that ssh tunnel to a other couchbase cluster one is the dev cluster one is a production cluster.
